Letters Patent No. 111,846, dated February 14, 1871.

IMPROVEMENT IN PEN-HOLDERS.

The Schedule referred to in these `Letters Patent and making parl: of the same.

To all to whom it may concern:

Be it known that I, ISAAC Jueces, of the city of N ew York, am in possession of an invention for Improvements in Pen-Holders and Pens, and do hereby declare the nature of the said invention, and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement thereof', that is to say:

'My improvements in pen-holders have i'or their object the production ot a voltaic or electric current in the lingers of a writer when holding the pen-holder, which voltaic orv electric cul'rcnt gives great steadincss to the hand of a nervous person using the penholder.

In constructing pen-holders according to my invention, I make the metallic or barrel part of the penholders of'two concentric tubes, the inner one being ot' zinc, and the outer one of copper, silver, o1' other metal or alloy which will form a volt-aio couple with zinc.

'.Lhe inner or Zinc tube is longer than thc cuter or copper tube, the protruding part of the zinc tube' being halt' cut away, and consequently sinni-tubular, in tigurc.

The outer or copper tubehas a series ot' elliptical or other-shaped pcrihrations in it, ,of a size about equal to the area ot' the portion ot the holder griped by the fingers and thumb respectively, the said perforations being so disposed that in whatever position the pen-holder is held by the writer, either the iirst or second linger, or thumb, or more than one of them, being presented Ato one or more ot the said perforations, come in contact with the zinc as well as the copper.

.Lhc moisture of the skin is suiticient, under the circumstance described, .to set up a gentle voltaic or elect-ric current, which gives steadiness to the hand of a nervous person using the pen-holder.

The contact of a metallic pen with the two metals oi' the pen-holder would interfere with their roltaic action, and hence it is necessary to avoid the connecting ofthe pen with the holder by the insertion ot"1 the heel part ofthe pen between the zinc and copper tubes offthe holder; and my improvement in pens consists in forming the said heel part much wider than usual, and doubling or folding its edges so as to enable the said edges to clip the semieircular protruding part ot' the zinc tube, hereiuheibre described, of the holder.

An ordinary quill-pen, with a portion oi' the quill lei't to i'orm a barrel, muy be used with a pen-holder constructed according to my invention.

Having explained the nature ot' my invention, l

will proceed to describe, with reference to the accom-v panying drawing, the manner in which the same is to be pertbrmed.

Figure l represents in side elevation, and

Figure 2, in longitudinal section, a pen-holder made according to my invention Figures 3 and 4 represent the two tubes of which the barrel part of the pen-holder is composed;

Figure i represents a pen made according to my invention, in combination with my improved penholder; i

ligurc 6 represents the pen separately; and

Figure 7 represents the blank from which the pen is made.

rlhe same letters of reference indicate the same parts in each figure of the drawinf.

The metallic or barrel part of the pen-holder is made ot' the twoconcentric tubes a b, the inner tube o being ot' zinc, and the outer tube l) of copper or other metal or allor which will form a voltaic couple with zine.

The two tubes a b ot' the compound holder are secured together by the indentations at o, or they mayv be secured together in any other convenient way.

The inner zinc tube a, is longer than the outer copper tube b, the protruding end, marked at of the said zinc tube (t, being of a semi-tubular figure.

ln the outer copper tube b is a series of elliptical perforations, d d, by means of winch perforations when the holder is griped for writing either the first or second linger or thumb, or more than one of them, come in contact with the two metals ot' the compound pen-holder (t b.

The pen c is provided with a semi-tubular heel, j, the said heel f being of such a size as will readily lit upon or clip the protruding semi-tubular part a2 of the zinc tube a, as illustrated in tigl 5.

The semi-tubular heel f ot' the pen c is made trom the blank, fig. 7, by doubling or bending the edges et' the wide part g of the said blank into the semi-tubular igure, best seen in the end elevation ot' the pen, iig. (i.

By using a metallic pen of the construction described with my improved pen-holder, the contact of thc said pen with the two metals ot' the pen-holder is avoided, and the voltaic action of the said peu-holder is consequently not interferedwith.

When the pen-holder is held in writing, one or more of the fingers and thumb come in contact with the zinc and copper tubes (t l), by means of the perforations d d in the outer copper tube I).

rlhe moisture of the skin where such cont-act takes place causes a gentle voltaic or electric current to be set up, which gives steadiness to the hand of a nervous person' using the penholde1'.

The positions of the two tubes (t la of the pen-holder may be reversed, that is, the copper tube b may be the inner tube, and the zinc tube a the outer tube; `but I prefer the arrangement of parts represented.

Having now described the nature of my invention, and the manner in which the same is to be performed, I Wish it to he understood that I do not limit myself to the precise details herein described and illustrated, as the same may be varied without departing from the nature of my invention; but

That I cla-im ns my invention isl. A metallic pemholder, composed ,of two con..- centrio tubes, one being of zinc, 4the other of copper or other metal or alloy which will form a. voltaic couple with zinc, the outer tube being perforated to permit, when the pen-holder is griped for writing, the fingers and thumb, or one or more of them, to

come in Contact with the two metals of which the compound pen-holder is composed, substantially ns and for the'purposes shown and described.

2. The combination of theherein-described penholder and the pen, subst'ftntnlly in the manner speelfed, so that the pen shall be in Contact with but one of the met-tls of which the holder is composed, substantially ns and for the purposes set forth.
